Background Information

TSG101(Tumor susceptibility gene 101 protein) is essential for endosomal sorting, membrane receptor degradation and the final stages of cytokinesis. It plays a crucial role for cell proliferation and cell survival. TSG101 has been identified as a candidate tumor suppressor gene and belongs to the ubiquitin-conjugating enzyme family. TSG101 is a marker for exosome. This protein has 2 isoforms produced by alternative splicing with the molecular mass of 44 and 32 kDa.

The antibody recognize the exosomal marker TSG101 as claimed. We tested it by Western blotting in our exosome preps isolated from murine brains and it gave the signal at the correct molecular weight in the fractions that are enriched in exosomes, so it seems to be specific. However, we report here some drawbacks that we have experienced using this antibody (see the file attached):1. There is a strong cross-reactivity of the antibody with the molecular weight marker we use (The Bio-Rad Dual Color Standard, cat. number 1610374)2. The signal over noise ratio is a little low (the background coming from the membrane is pretty high)
